fix: scope quote normalization to CLI input

[jeffrey-takuma]

Summary

Scope quote normalization to CLI input instead of the library API.

This moves the outer-quote normalization logic out of lib/concurrently.ts and into the CLI entrypoint, so well-formed shell commands keep their quotes when using the library API.

Closes #582

Changes

• remove StripQuotes from lib/concurrently.ts
• add bin/normalize-cli-command.ts for CLI-only command normalization
• normalize CLI commands in bin/index.ts before calling concurrently()
• add coverage for CLI normalization in bin/normalize-cli-command.spec.ts
• add coverage for preserving quotes in the library API in lib/concurrently.spec.ts
• add a thin CLI integration test in bin/index.spec.ts

Tests

• pnpm test

Opened this PR for #582.

The test jobs are passing on the PR. The only failing check seems to be the coverage upload step, which is currently returning a Coveralls 504 timeout.
